To all whom it may concern.:

Be it known that I, GEORGE W. ARPEE, a citizen of the United States, residing in Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Faucets for Oil-Cans, of which the following is a specification.

My invention relates to improvements in faucets for coal-oil cans and similar packages' from which liquid is to be drawn in larger or smaller quantities from time to time into smaller Vessels; and the same consist in certain novel construction of vent-tube having a valved aperture at some point between its inlet-end and its outletfend, in combination with the faucet of a can, as hereinafter fully set forth, by which air is admitted to the can during the operation of drawing a portion of the contents into a small -vessel but is cut-off to stop the flow of liquid as soon as the vessel is filled.

The object sought. to be attained in the present invention is to clear out the vent-tube at the end of each operation or cause it to discharge whatever liquid'is drawn up and remains in the lower end of the vent-tube after the faucetis closed and which, unless removed will act to seal the passage and interfere with the successful operation ofthe vent-tube.

The following description explains the nature of niysaid improvements and the manner in which I proceed to apply the same for use both with a compression-faucet of the kind most generally used on coal-oil cans and also with a plug-faucet, the same being represented in the accompanying drawings forin- -ing part of this specification to which reference is made by letters.

Figure l of the drawings representsacoaloil can with a compression-faucet having my improvements applied to it, the view beinga side elevation of the can with portions shown in section, and the body of the faucet broken away to uncover the valve. Fig. 2 is a sideview on an enlarged scale showing the Venttube and the faucet in section. Fig. 3 is a front view of the faucet, vent tube and connected parts shown in Fig. 1. Figs. 4, 5 and 6 represent one mode of applying my improvement to a plug-faucet. In these views Figxt is a vertical longitudinal section, Fig. 5 a horizontal section taken through the line Fig.

4 and Fig. 6 is a vertical section on the line Fig. 5 but with the plug turned in position to close the faucet.

A indicates a continuous vent-passage eX- tending from the space above the liquid in the can down to the end of the spout or nose of a faucet F by which the contents of the can are drawn off in larger or smaller quantities from time to time into smaller vessels.

4C Figs. l and 2 indicates a portion of an ordinary coal-oil `can with a compression-faucet Ffor filling a lamp directly from the can; one opening from the v'ent passage is at ax at the top of this can and the other end a is situated at the end of the faucet about on a line with, or just above, the end of the spout or nose. This passage is formed by fixing a tube of small bore either upon the inside or the outside of the can and carrying the lower continue to flow as long as `the lower enda But byV of the vent-passage remains open'.

end down along the faucet; or it may be holding the lamp or vessel to betllled 4in such position under the faucet that the liquid will cover the end of the vent when the required quantity has been drawn the further flow will be cut-off, and if the faucet be closed before the vessel is removed no over-flow or waste of liquid will take place. In this operation, however, it will be found that the lower end of the vent-passage retains, or becomes gorged with, the liquid by which it is covered at such time, and the smallv quantity being held in the passage by atmospheric pressure will stop the vent and prevent its further action when another vessel is to be filled, unless the end of the passage is previously cleared or made to disgorge the liquid. To secure continuous and certain action of the vent-passage therefore I make an air inlet or opening bin the tube A above the point where the passage becomes gorged or clicked. This openingI control by a valve B, which is so connected with the valve stem of the faucet that when the faucet is turned on the opening b is closed, but when the faucet is shut the opening is uncovered and the vent-passage isopenedto the atmosphere above the open lower end.

Figs. l, 2 and 3 illustrate the manner in which I control the opening by a compression-faucet. The valve lu is set on the upper end of an upright leverBX working on apivot d, while the lower end of the lever is brought downwardly in a curve to set against the back of the knob or head FX of the faucet stem. A spring cl2 under the curved arm of the lever holds the lower end against the knob. Suitable movement of the lever is thus obtained as the screw-stem of the faucet is turned in or out to open or close the opening. The first mentioned position is shown in Fig. l where the faucet is closed and the air inlet opened, and the second position is shown in Fig. 2 where the faucet is open and the opening in the vent-passage closed.

Figs. 4, 5 and G show the manner in which I control the relief-opening b in the vent passage A by a plug-faucet F. In this construetion the aperture b is made in a portion A of the vent-passage which here extends along the body of the faucet F at one side of the stein or plug F2 so that the aperture opens hrough the seat of the stem or plug and a perpendicular port or passage b2 is made in the body of the stein at such point on its circumference that when the stem is set to close the faucet this port comes directly in line with the aperture b and opens it to the atmosphere, but when the plug is turned to draw liquid the port is set away from the aperture and a continuous vent-passage is established from the end of the faucet to the top ofthe can. The pin fX on the stem or plug and the shoulders g, g on the neck of the faucet are used to limit the rotative movement of the plug and bring it to rest at one or the other of the positions above mentioned.

As thus arranged for operation it will be seen that the tube A forms a coutin nous ven tpassage from the end of the faucet up into the space over the liquid when the faucet is turned on; and on the other hand, this passage is opened to the atmosphere above the gorging point by the act of shutting off the flow of liquid at the faucet.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with an air-tight can orliquid-holder, and a faucet for drawing off the contents thereof, of a vent-tube or passage extending from the end of the faucet up into the space over the liquid within the can, said passage having an aperturelocated at a point above the lower end thereof as described, and a valve controlled by the stem of the faucet and adapted to close said aperture when the faucet is opened and to open said aperture to admit air into the passage when the faucet is closed, substantially as and for the purpose set forth.

2. The combination with the faucet F F,ot` the vent-tube A having an air inlet opening between its lower inlet-end and its upper end, and a valve adapted to control said i11- let and operated by the movement of the stem of the faucet, as described, to close the inlet when the faucet is opened and to open the inlet when the faucet is closed, substantially as and for the purpose set forth.

3. The combination with an airtight can having a nozzle, a compression faucet for closing said nozzle, and a head on the stem of said faucet; of a vent-tube opening at one end into the top of the can and at the other end alongside said nozzle, this tube having an air-inlet opening between its ends, a lever pivoted between its ends to the can with its lower end behind said head and itsupper cud opposite said air-inlet, and a spring behind said lever to normally close said air-inlet, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
